Issues using AllowedExtraContent

[Thierry]

Hi, I have issues to correctly parameter the "allowedExtraContent" option. In my textarea there is custom HTML tag that I want to keep.

There is an example : <foo>bar</foo> <foo attr="value"/>

I successfully manage to keep the first one using : extraAllowedContent : 'foo' But the I can't manage to keep the second one.

Thanks for your help.

Simply: extraAllowedContent: 'foo[value]'. And that's all.

I think @thierry-finemedia is also talking about self-closing custom tags.

CKEditor doesn't support custom tags. It is impossible at the moment to use block-level custom-tags #10340.

If you want to use self-closing tags you need to change the ​http://docs.ckeditor.com/#!/api/CKEDITOR.dtd (​http://docs.ckeditor.com/#!/api/CKEDITOR.dtd-property-S-empty to solve this issue) if you want to load custom tags. Remember that CKEditor is an HTML editor, not XML editor, so it's not guaranteed that every kind of markup will work.
